Onee-chan wa Game wo Suruto Hito ga Kawaru Vol 3,4 - Don't spoil it Yuuna!

Volumes 3 and 4 of Oneechan wa Game wo Suru to Hito ga Kawaru continue with another two solid volumes showing more of the antics of Yuuna Uesawa in her life of gaming and taking care of Toshitake, together with her friend Hime and Toshitake's classmate Mashiro.

As promised in the previous volume, there was a bigger presence of Chihiro's friends Hiromi and Yuki in these two volumes showing a bit more of the dynamics happening within the school. I'm honestly quite fond of this part especially, maybe even more than the main heroine Yuuna.

Living with Yuuna must be hard for Toshitake for various reasons, huge reasons, amazing reasons. You can see what I mean.

Overall I still think Mashiro is one I like more. I'm always liking the silent/quiet type like her.

At the same time we also got another weird character added to the mix, Takamiya Nasuno, who appears and interacts with the girls whenever a sports scene comes up. She appears once in a tennis segment and once in a golf one, both extremely fanservice-heavy scenes. Initially, I honestly didn't fully understand why she was appearing or who she was, and only later realized she is one of the main characters from the gag manga series Teekyuu, written by the same author, which I never had the chance to read.

One particular skit that I loved featured Yuuna and Toshitake alone playing a classic RPG, think of Dragon Quest I and II or something along those lines. Yuuna had played it already, and it was Toshitake's first experience trying out different things, picking weapons, and choosing allies.

Hime continues to be the center when it comes to dirty jokes and teasing. It's her character at this point and she strives for perfection in every skit!

Who wore it better? I'm honestly doubting that Yuuna and Hime are even wearing it to be honest, but still...

Yuuna kept barging in, trying to guide him to the right answers because she just couldn't control herself when she saw him making a bad decision. I know her feeling, and yet a part of me was saying, "Stop disturbing him; let him experience failure for once."

Overall, I think the series is okay up to this point, but it's in a hard spot when it comes to keeping people hooked for the long term. It has plenty of well-drawn fanservice and generally fun skits, but I don't think the characters have enough depth for me to get emotionally attached to.

Chihiro's friends (Hiromi and Yuki) have a very different size. Like poor girl, she's outclassed completely even if they have the same age.

Turns out taking care of an energetic kid is a lot harder than Yuuna and Hime were expecting. Just look at their energy being completely depleted!

In the next volume, Chihiro seems to be completely infatuated with Toshitake, hugging him and being overly close. Then there is a small picture showing her with yandere eyes, which makes me wonder if the protagonist will survive the end of the volume. I wasn't counting on the quiet Chihiro to go yandere, but it might be fun comedy...
